KAFKA-3414; Return of MetadataCache.getAliveBrokers should not be mutated
by cache updates
`Map.values` returns `DefaultValuesIterable` where the default
implementation of `toSeq` is (sadly) `toStream`. `Stream` is a lazy collection
and it can reflect changes to the underlying map before it's `forced`.
I verified that the test failed before my change.
